NGC 3509

NGC 3509 is a barred spiral galaxy in the constellation Leo about 357 million ly from Earth. It spans roughly 200,000 ly, about 2.0 times the width of our Milky Way. It is receding from us at about 7,636 km/s.

Because its light is 357 million ly from home, you are seeing NGC 3509 as it looked roughly 357 million years ago. The photons left before that much of history had passed, and are only now reaching us. This distance is estimated from the galaxy's redshift, so the lookback time is approximate.
